Description

Technical Field

[0001] The utility model relates to an anti-interference radio frequency connector, belonging to the technical field of radio frequency connectors. Background Art

[0002] A radio frequency connector is an electronic component used for radio frequency signal transmission, which is widely applied in fields such as communication equipment, radio equipment, microwave equipment, and aerospace. They can provide reliable electrical connections within a high-frequency range and generally have low insertion loss and reflection loss. The designs of radio frequency connectors are diverse, including coaxial connectors, waveguide connectors, etc., which can meet the frequency and power requirements of different systems and ensure the stability and performance of signal transmission.

[0003] For example, the publication number CN209183895U discloses a radio frequency connector, which includes a connector body, a protective shell arranged outside the connector body, and an insulator and a center spring pin arranged inside the connector body. It is characterized in that: several outer conductor spring pins are arranged around the center spring pin to form an electromagnetic shielding wall for the center spring pin. By arranging several outer conductor spring pins around the center spring pin to form an electromagnetic channel and using several outer conductor spring pins to form an electromagnetic wall, the contact reliability of the outer conductor can be improved simultaneously.

[0004] This radio frequency connector lacks an anti-interference structure, resulting in an unsatisfactory overall anti-interference effect. It will cause the signal to be easily affected by external electromagnetic interference during the signal transmission process, leading to problems such as signal distortion, increased noise, and reduced transmission efficiency. This will not only affect the stability and reliability of the communication system but may also cause data transmission errors, communication interruptions, and even damage to equipment, thus seriously affecting the normal operation of the communication system and the user experience.

[0005] Therefore, an anti-interference radio frequency connector is proposed. Summary of the Utility Model

[0006] In view of this, the utility model provides an anti-interference radio frequency connector to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the utility model is realized as follows: an anti-interference radio frequency connector includes a radio frequency connector body, and the radio frequency connector body includes a silver-plated inner conductor, a first functional layer, and a second functional layer. The first functional layer includes a beryllium bronze elastic contact member and a PEI resin insulating layer, and the second functional layer includes a nickel-based alloy shielding layer and a ferrite material shell.

[0008] Further preferably, the first functional layer is arranged on the outer surface of the silver-plated inner conductor, and the second functional layer is arranged on the outer surface of the first functional layer.

[0009] Further preferably, the beryllium bronze elastic contact member is disposed on the outer surface of the silver-plated inner conductor, and the PEI resin insulating layer is disposed on the outer surface of the beryllium bronze elastic contact member.

[0010] Further preferably, the nickel-based alloy shielding layer is disposed on the outer surface of the PEI resin insulating layer, and the ferrite material housing is disposed on the outer surface of the nickel-based alloy shielding layer.

[0011] Further preferably, the beryllium bronze elastic contact member and the PEI resin insulating layer have the same thickness, and the thickness is 0.9 mm - 1.1 mm.

[0012] Further preferably, the nickel-based alloy shielding layer and the ferrite material housing have the same thickness, and the thickness is 0.3 mm - 0.5 mm.

[0013] Due to the adoption of the above technical solutions in the embodiments of the present invention, the following advantages are achieved:

[0014] First, the present invention provides a first functional layer including a beryllium bronze elastic contact member and a PEI resin insulating layer. Among them, the beryllium bronze elastic contact member has good electrical performance and heat transfer performance, strong fatigue resistance, and strong corrosion resistance. It can ensure stable electrical contact while effectively resisting the performance degradation caused by the external environment and long-term use. Its fatigue resistance enables it to maintain stable electrical performance in high-frequency vibration and shock environments, thereby improving the anti-interference ability of the RF connector body. The PEI resin insulating layer has excellent high-temperature stability, infrared transmittance, and metallization ability. It can effectively isolate the interference between RF signals and the external environment while maintaining the stable transmission of signals. Its high-temperature stability enables the RF connector body to work normally in high-temperature environments, and its metallization ability can effectively conduct electromagnetic signals, reducing signal attenuation and interference.

[0015] Second, the present invention provides a second functional layer including a nickel-based alloy shielding layer and a ferrite material housing. Among them, the nickel-based alloy shielding layer has good electrical conductivity and shielding performance. It can isolate electromagnetic waves and radiation interference, effectively prevent external electromagnetic wave interference, and ensure that the RF signal is not affected by the outside world during transmission inside the RF connector body. At the same time, its good electrical conductivity can also effectively prevent electromagnetic leakage inside the RF connector body, further improving the anti-interference performance of the RF connector body. The ferrite material housing has high magnetic permeability and high-frequency magnetic permeability characteristics. It can effectively block the propagation of electromagnetic waves, isolate external electromagnetic wave interference, and provide a stable electromagnetic environment for the RF connector body. At the same time, its high magnetic permeability characteristics can also effectively absorb and dissipate the electromagnetic radiation inside the RF connector body, further reducing the impact of electromagnetic interference on the performance of the RF connector body.

[0016] III. By providing a silver-plated inner conductor, the utility model can effectively reduce the signal transmission loss, ensure a high signal-to-noise ratio when the radio frequency signal is transmitted inside the radio frequency connector body, thereby improving the anti-interference performance of the radio frequency connector body.
